Substance abuse is also associated with poor academic performance and aspirations and prolonged stay at school buy discount himplasia 30caps on line. Sutherland and Shephered (2001) have shown that drug use is associated with academic difficulties buy 30 caps himplasia visa, absenteeism and dropping out of school cheap himplasia 30 caps without a prescription. For example cannabis use buy cheap himplasia 30 caps line, which is a drug of choice among South Africa youth has been shown that it generally interferes with learning, short-term memory and psychomotor skills. Melisa et al (2014) reported that methamphetamine (“tik”) had “adverse effects on mental, physical, and economic well-being, and limited future opportunities through school drop-out and incarceration” of drug users in the Western Cape Province. The same study implicated tik use to household conflict, with negative consequences on children, “including neglect and poor birth outcomes”. At a community level, respondents linked tik use to increased rates of crime, violence and corruption, which undercut community cohesion. Consequences to Society Substance abuse certainly means the energies, creativity and talents of the youths are not harnessed. Substance abuse is linked to unemployment, crime, physical inactivity and even premature deaths. The National Drug Master Plan (2012-2016) estimates the costs of illicit drugs to the South African economy at 6. Other major costs such as drug related violence, injuries, deaths, disease, law enforcement and lost productivity remain largely unquantified. Melisa et al (2014) noted that at the community level, tik use was 23 associated with “increased rates of crime, violence and corruption, which undercut community cohesion”. Although these statistics do not directly speak to the youth; they point to a serious national burden. Missing connections in Literature Other than the above, literature in South Africa is silent on the harm substance abuse has on others (friends, and colleagues) (Ramsoomar, 2015). Further research is required to establish the effects of substance abuse by young people on the quality of family life, pressures on family finances, family stress levels, family or friend disruptions, emotional and psychological impacts on families, divorces, theft from family and friends, etc 24 Section 6 Approaches to combating drug use among Youth The above review of literature shows that youth substance abuse is a multidimensional challenge that requires a multifaceted and integrated gamut of interventions. Bronfenbrenner’s socio-ecological framework becomes handy when analysing interventions as it allows the targeting of interventions to all risk factors at all levels: be it individual, micro, mesosystem and exosystem. Thwala (2005) has noted that for any intervention to be successful, it should be underpinned by the following set of principles:  Principle 1: Interventions should promote protective factors and seek to lessen risk factors. Individual Measures At the individual level, literature proposes many strategies for dealing with substance abuse. According to Brook, (2012) effective strategies at this level target the youth directly and also take into account peer influence. Brook observes “that combating substance use should involve reversing positive attitudes to drugs and dealing with personality dispositions that predispose them to drug use, and addressing symptoms of mental health problems that may cause and/or exacerbate the abuse of substances…. Young people should be trained on how to resist peer pressure as this is the single most important risk factor for the youth. Harker, at al (2008) also suggests that it is 25 important to have prevention programmes that attempt to engage the minds of the youth to avoid boredom. Such activities include life skills programmes, vocational training services, youth sport and recreational activities. Thwala (2005), highlights the following key elements for successful prevention programmes:  Balancing negative and positive effects of substance abuse  Improve social skills,  Provide healthy alternatives to drugs,  Focusing on harm reduction to those already affected,  Emphasise quality of life changes  Have interactive programmes and include peers and parents. As young people spend most their time at school, school-based programmes are essential. At school Harker, Myers and Parry (2008) caution against once-off training sessions by specialists as these may have perverse outcomes. They note that once off lectures have proved to be ineffective and instead stimulate more interests on substance abuse. Scare tactics, where inducing fear among substance abusers and immediate families by exaggerating the risks and relative dangers of illegal drugs, or misusing statistics to drive scare messages home, should also be avoided as they have rarely influenced behaviours in a positive way (United Nations Office on Drugs and Crime for Southern Africa 2004). When adolescents discover that they have been misled they subsequently reject any information on drugs from official channels Microsystem: Literature is clear that successful interventions are those that target the youth concurrently with their peers, parents and families. Improving parenting skills and behaviours is essential when trying to address a youth’s immediate toxic environment.

This method will obviously not work if the cause of the problem is severe diarrhoea generic 30caps himplasia fast delivery. A lubricated plastic tube with a blunt end (a large urinary catheter or nasogastric tube is ideal) should be passed through the anus into the rectum for about 9 inches order himplasia 30 caps on-line. A longer length of tubing and a drip bag or funnel should be attached to the end and elevated discount himplasia 30caps with visa. If 200 ml is tolerated it can be worth increasing the volume slightly or reducing the time to 3 1/2 or 3 hrs 30 caps himplasia with visa. A rectum full of faeces does not absorb water very well, so the amounts may need to be reduced, but given more frequently. Amputation was one of the most common surgical procedures of the last two centuries – life threatening infection from wounds and compound fractures were common, and in the absence of antibiotics amputation was the only option. Amputation in an austere situation needs to be viewed as something only performed to save a life. All attempts should be made to save the knee and elbow joints even if this means having a short stump. Extremities with severe involvement of the skin, muscle, and bone with anaesthetic terminus or irreparable nerve injury c. Under combat conditions the most acceptable form of amputation is the open circular technique 1. A circumferential incision is made through the skin and deep fascia at the lowest viable level. The muscle bundles are exposed and then divided circumferentially at the new level of the skin edge. Upward pressure is placed on the proximal muscle stump and the bone is transacted at a still higher level. The surgical wound will have the appearance of an inverted cone - 174 - Survival and Austere Medicine: An Introduction 4. Cold injuries are not indications for amputation – wait until the edges demarcate d. A layer of fine mesh gauze is placed over the wound and the recess is packed loosely with fluffed gauze. A stockinette is the applied over the stump securing the stockinette above the stump using adhesive. The stump is wrapped with ace wraps using compression decreasing proximally and 5-6lbs traction is applied. Superglue will effectively close wounds – with the same provisos as medical tissue adhesives (see chapter). However superglue is not sterile (likely to have little impact) and different brands have different preservatives which may be harmful to injured tissue. It is likely to be no problem for small wounds, but there is a potential for toxicity when large amounts are used. Hypothermia Note: precautions need to be taken where the person concerned has been in the extreme cold, either the snow or very cold water. Severe hypothermia causes a profound slowing in the body’s metabolism and as a consequence can mimic death. A dead person should be buried quickly in a reasonably deep grave to avoid predation by scavengers. Most religions have short rites for the burying of the dead but for the non-religious a favourite poem may be appropriate. This becomes important for legal reasons should things return to normal or in the case of an isolated expedition for the coroner on your return. Gastroenteritis is still a killer in the third world especially for young children (We include typhoid, cholera, Giardia, salmonella, "food poisoning" etc, under the general heading gastroenteritis). The most important preventive action you can take in preventing gastroenteritis is to wash your hands following defecation. Also hands should be washed before handling food, dealing with the sick or babies and infants.

Over the years himplasia 30caps discount, the development of new technologies discount himplasia 30 caps online, new procedures and new uses has quickened its pace discount himplasia 30caps with amex. This has resulted in medical radiation exposures becoming a very significant component of the total radiation exposure of humans order himplasia 30 caps visa. It is currently estimated that every single day, 10 million people receive diagnostic, therapeutic or interventional medical radiation procedures. While the majority of these procedures are performed safely and appropriately, there are situations throughout the world where radiation safety is either lacking or deficient. More than 600 participants have registered for this conference, representing 88 Member States and 17 organizations. I say ‘representing’: I know that many more of our colleagues from all stakeholder groups would have liked very much to join our discussions this week. You know that unintended exposure of patients and medical staff can arise from unsafe design or from inappropriate use of medical technology. The number of occupationally exposed workers is much higher in medicine than in any other professional field, and individual occupational exposure also varies widely among those involved in medical care. The Malaga conference in 2001, which many of you may have attended, resulted in the International Action Plan on the Radiation Protection of Patients. This web site receives more than 1 million hits per month and is now also employing social media to increase its outreach. It has been possible to realize these successful developments only with the cooperation of our sister United Nations organizations, regional organizations such as the European Commission and the Pan American Health Organization, professional societies and, not least of all, the contributed expertise of renowned professionals such as yourselves. Together, we can ensure that the highest international radiation safety standards are developed and brought into force worldwide. But, observable and unmistakable trends stimulate the need to pursue further actions to improve safety for patients and health workers. The more than 200 submitted papers, 8 topical sessions and 4 round tables should provide fruitful discussions to guide our future work. This is a single-track conference, which means that each of you is assured the possibility to follow all sessions and to participate in all discussions. Together in this conference, we can arrive at a point which will guide our work in the next decade. It is for all of us, together, to formulate the call to action for the next decade. Let us ensure that the work that we started in our respective institutes and organizations, and the focus of our discussions this week, will strongly contribute to instilling safety culture and promoting patient and worker safety in medicine. But, in the same way as for reactor safety, understanding the issues and developing standards to answer them is not enough. I particularly thank the Government of Germany for hosting this event through the Federal Ministry for the Environment, Nature Conservation and Nuclear Safety. I wish to commend the Conference President, as well as the Chairperson and members of the Programme Committee, for making today’s event a reality by putting together the outstanding programme you will develop during the next five days. Radiation protection in medicine is an essential component of good medical practice that has established itself as a subject of interest not only for radiation safety bodies and health authorities but also for policy makers, health care providers, researchers, manufacturers, patients and the general public. There is a global trend of a major increase in the number of radiological procedures, medical uses of ionizing radiation being the largest artificial source of radiation exposure today. Ionizing radiation has become one of the most important diagnostic tools and an essential component of cancer treatment. On the benefits side, new technologies, applications and equipment are constantly being developed to improve the safety and efficacy of procedures. At the same time, incorrect or inappropriate handling of these increasingly complex technologies can also introduce potential health hazards for patients and staff. This demands public health policies that both recognize the multiple health benefits that can be obtained, while addressing and minimizing health risks. Management of such risks depends on two principles of radiation protection: justification for prescribing each procedure, and optimization of protection to manage the radiation dose commensurate with the medical purpose. When choosing the best medical imaging procedure for a given clinical condition, doctors have to take appropriate decisions, accounting for both benefits and risks. Primary prevention requires the improvement of radiation safety culture by health care providers.
